I know the vacum almost fits, I do really like Krown even on my slightly rusted axles it almosted looked like they were painted black after the Krown, I got my first oiling done at walmart. I think the Krown stuff is far better, although the walmart junk kinda dries to a waxy finish. The guy doing it at both places was needless to say kinda an idiot. First thing I've always done, if they don't let me under there lift, is find a nice dry spot in there parking lots and look at everything, only been one time I havin't went back in a bitched. When I pay 100 bucks for an oiling I expect it to be very oily. The Krown guys are usally more professional than other places, but make sure you take a look yourself, also as I said give you frame rails a good cleaning before you go in and leave all the pulgs out and ask them to do and expecially good job on them.
I love the snow wheeling so thats why I am so crazy about oiling, I like krown because if you do want touch ups for any reason, ie new floor boards, body work, dry spots etc they will do it no questions asked unless your year is up of course. I got mine done in St. Thomas, Ontario. I don't think there is anyone on the board that lives around here as the guy at krown had never seen a BJ before.
cheers
